Question

我正在将我的应用从Play 2.0.4迁移到2.1.0。 Play 2.1无法识别视图中的flash，会话或请求，从而产生编译错误

如何在play-2.1.0

中表示play-2.0.4中的以下代码

一个。闪光

@if(flash.contains("success")) {
        <p class="success">@flash.get("success")</p>

        }

B.session -----

@if(nav == "signup" && session.get("sitetype")=="public")

℃。请求

var chatSocket = new WS("@routes.Chat.chat(username).webSocketURL(request)")

非常感谢帮助。

Answer 1

添加appdendency和导入模板帮助

val appDependencies = Seq（ javaCore，“org.apache.commons”％“commons-email”％“1.3.1”

val main = play.Project（appName，appVersion，appDependencies） .settings（ templatesImport ++ = Seq（“play.mvc.Http.Context.Implicit._”））

Answer 2

派对有点晚了，但我有C节的解决方案。

在chatRoom.scala.html的顶部添加@(username: String)(implicit request: play.mvc.Http.Request)

这会带来错误，因为需要传递请求。您可能正在调用与ok(chat.render(username));类似的代码，将其更改为ok(chat.render(username, request()));

在plugin.sbt中，添加以下行：javacOptions += "-Xlint:deprecation"
